Claims.

This invention relates to car dumping app-aratus for transferring coalor other friable ma.- terial from one car to another or toa suitablereceptacle.

One of the prime objects of the invention is to provide a car dumpingmechanism for dumping or transferring material from one car into anotherand in such manner that the material is not dropped or broken, but isgently rolled and discharged in a steady controlled stream so that anabsolute minimum of fines and slack is produced.

Another object is to provide an intermediate material receiving meansinto which the material is dumped and which is actuated in propersequence to smoothly and gently deposit the load in a transfer car orreceptacle provided for receiving it.

A further object is to provide a car dumper construction of suchcharacter that the dumping operation occasions a minimum movement of theload, and consequently minimum amount of breakage.

V A still further object is toprovide simple and practical means fortransferring coal or other friable material from one car to another ortoi a suitable receptacle which is composed of few parts, all ofsubstantial construction, and which is economical to assemble andoperate.

With the above and other objects in View,

the present invention consists in the combination and arrangement ofparts, hereinafter more fully described, illustrated in the accompanyingdrawings, and particularly pointed out in the appended claims, it beingunderstood that changes may be made in the form, size, proportion, andminor details of construction, without departing from the spirit, orsacrificing any of the advantages of the invention.

In the drawings- Fig. l is an end view of our improved car dumpermechanism, the solid lines showing the loaded car in position on thecradle, and the hopper in position on the transfer car, the broken linesshowing the position of the loaded car and transfer hopper whendischarging into said hop per.

ing the hopper in position for discharging into the transfer car.

Fig. 4 is a. fragmentary sectional view showing the hopper indischarging position in the transfer car.

Fig. 5 is an enlarged fragmentary view illustrating one end of thehopper and one of the conveyers, the hopper being shown in section.

Fig. 6 is a fragmentary detail of the pivoted hopper, the broken linesshowing the gates on the one side swung down to permit discharge of theload.

In the handling of coal on other friable material it is essential thatthe coal or material be controlled during the dumping operation so thatit does not fall an appreciable distance, and so that large chunks donot gather momentum and crash into the coal stream or receivingreceptacle and thus cause considerable breakage. To eliminate theforming of fines and slack, which command a lower price than does theunbroken material, it is necessary that the discharging or movingmaterial flow and roll in a steady stream, and that the mechanism be sodesigned and operated that the coal does not drop, but that it gentlyfiows and rolls from one receptacle or depository into another, and wehave, therefore, designed simple, practical, and economical means forcontrolling the discharging and moving material so that it fiows androlls as above described, and with a, minimum of movement and breakage.

Referring now more particularly to the drawings in which we have shownone embodiment of our invention, the numeral 8 indicates the fabricatedstructure or tower of a car dumper of conventional design; this includesa cradle 9 provided with tracks ill adapted to accommodate aconventional car I I in which the material to be transferred is loaded.A side wall l2 forms a part of the cradle, and the car I! is shiftedagainst said wall prior to the elevation and dumping thereof. Spacedapart clamps l3 are pivotally mounted on the cradle 9, and a curtain Mis secured thereto and forms a closure for the open top of the car toconfine the coal as the car is tilted, a lip section [5 being formed onone edge of the curtain, all as shown and described in an applicationfiled by Ernest W. Taylor under date of May 8, 1933, Serial No. 669,823,and when the car is tilted, this lip section swings outward- 1y (seeFig. 3 of the drawings) to permit the dis charge of the coal, meteringand confining the stream so that an even, controlled, and steady fiow isassured.

the coal from the tilted car and then swung down and into the transfercar for depositingthe load therein.

The hopper I8 is formed as clearly shown in Figs. 3, 4, and 6 of thedrawings, being substan:

tially V-shaped in cross section, and having an angled lip 20 on theinner edge thereof, gates 2| being provided on the lower endto'permitjithe, discharge of the load when the hopper is lowered toposition in the transfer car, and an additional gate 22 is providedonthe inner-edge'to assistin this discharging operation when, the hopperis swung upwardly, and as shownin Fig, 6.

Sheaves 23 are mountedon .bracesw24-which are secured to the outer edgeof the hopper to accommodate the rope systemzused for controlling theswinging thereof, and in a manner to be presently described.

A deflector plate 25 forms a part of the superstructure and guides thedischarging material into. the hopper as the car is beingtilted, and

a machinery house 26 is provided on the frame,

together with anoperator's house 21 so thatthe operator may be properlylocated to control the sequence of operation. 1

The equipment is. designed to accommodate and handle either one largecapacity car. or two small capacity cars simultaneously, and in order toaccommodate the two small capacity cars, the hopper is of greater lengththan the transfer car,

and we, therefore, provide a conveyer 28at'eachend of the hopper so thatas the material is being discharged from the car, these conveyers can bedriven, thus conveying the coal from the-end sections to the hopperedcenter sections 29 of the hopper, and which are provided with the gates2| and'22 as above described; deflector plates 30 are also provided ineach end of the hopper for deflecting the material onto the conveyers. VThe mechanism for shifting, clamping, and tilting the car, together withthe cable arrangement for raising, etc.'are of conventional design, andit is not deemed necessary to show or to describe them in detail, asthis invention is directed to the means for transferring thematerialfrom the loaded car into the transfer car. The hopper is controlled byrneans ofthe; cables 3|, anchored to the hangers 32, thence leading downand around the sheave 23, thence up and around the sheave 33, thencedown and around the sheave 34, and up and over the-sheave 35, and beingwound on a winding drum 36 as usual, thence the cable leadsback and overthe sheave 31, and counterweights (not shown) are connected thereto.

Inpractice the loaded car is onto the cradle and clamped in position; itis then'carried upwardly in the dumper, and rate. certain predeterminedpoint is tilted, the hopper l8'being swung upwardly and into position toreceive the contents-of the car; when thecar is sufliciently tilted, thecurtain lip I5" begins to swing down,

and the coal begins to roll and flow in'a steady stream into the hopper,theh'opper then begins to swing downwardly as it fills, until the entirecontent of the car is deposited in said hopper, and where two smallcapacity cars are simultaneously handled, the conveyers 21 are operatedto carry the coal from the end sections to the hoppered center section.

The empty car now is swung back and is lowered, while the loaded hopperis swung down and into the transfer car, the gates 2| are then swungopen so that'the coal flows into the transfer can the hopper is thenagain swung upwardly so that the coal remains deposited in thetransfencar-there has been a minimum movement of the coal, no drops orcrushing, and the entire operation has. been smooth and easy.

, It will, of course, be understood that the shape of the hopper andtransfer car can be varied as desired, and that any other suitablereceptacle :maybe substituted for the transfer car.

Frornthe foregoing description it will be obvious that we have perfecteda very simple, practical, substantial and economical material handlingapparatus for handling coal and. other friable materials.
